摘要
本文比较研究了酵母和奶粉样品的四种消化方法，在ＨＮＯ３－Ｈ２ＳＯ４，ＨＮＯ３－ＨＣｌＯ４和ＨＮＯ３－Ｈ２Ｏ２三种凯氏瓶法中，ＨＮＯ３－Ｈ２Ｏ２法较好，而在ＨＮＯ３－Ｈ２Ｏ２的凯氏瓶和微波炉ＰＴＦＥ高压密封罐消化法中，微波炉消化法的速度快、简便、准确度好．
In this work, four digestive methods of yeast and powdered milk wilk were compared. Fe, Mg, Cu, Ca and Mn weve determined by flame atomic absorption spectrometry. HNO3-H2O2 digestive method was found better in open vessel digestive meth ods than HNO3-H2SO4 and HNO3-HClO4 ones. Hign pressure microwave dige stive method in HNO3-H2O2. is a far puick, simple and convenient methcd of all.
